Huiji Mountain, a thousand rocks compete for the show, ten thousand ravines compete for the stream, the mountains are stacked, the grass and trees are verdant on it, if the clouds are steaming.

In the early summer morning, under the shade of trees, the "Zheng's Iron Workshop" at the foot of the mountain is not hot at all, and the air is fresh and refreshing.

Zhao Hong walked from the mountain path, and Tian Yi, who was leading the horse, and a few other guards behind him. Everyone was sweating, but the mountains and rivers were beautiful, and the spirit was good.

A few months have passed, running back and forth, following Li Tang and others to practice martial arts and archery, Zhao Hong has become a lot darker, but he is much more energetic.

The iron smelting of Zheng's Iron Mill is already on the right track, and there is no need for him to worry about it. He came today to forge artillery

According to Li Tang, several artillery pieces had already been built, and he came to see the effect.

"Your Highness, I'm dismissed from the official position, and I'm still following you, I'm afraid it's not appropriate, right? If it is seen by Shi Miyuan's people, I'm afraid it will be troublesome. ”

Tian Yi followed behind Zhao Hong, looking left and right, contemptible as if he was a thief.

The iron powder mill has been taken over by the Ordnance Department of the Ministry of Industry, and he is now a grass man, and it is inevitable that people will be criticized when he goes in and out here.

"I'm not afraid, you're afraid of a bird! I'll hire you to be my personal staff and personal bodyguard, and I'll pay for it myself, and that's all right! ”

Zhao Hong said angrily, despising Tian Yi and cowering.

There are some things that will be peaceful if you are not afraid.

"Tian Dalang, don't worry. Now that His Royal Highness is famous in Jinghua, those-stirring sticks just want to slander His Highness, and they have to weigh it carefully! ”

The guard Hu Datou led the horse and said in high spirits.

"Low profile! Low profile! ”

Xu Sheng looked at Zhao Hong, who was silent in front of him, and said seriously.

After a few months, many of Zhao Hong's mantras were accepted by these young guards.

I saw Zheng Hao sitting at the door of the iron mill, with a big round head crooked, like a frosted eggplant, and he was weak.

Zhao Hong couldn't help but smile.

"Lao Zheng, what's wrong, listless?"

It seems that the imperial court took away Zheng Fatzi's livelihood, and he was very resistant.

The imperial court paid him a "transfer fee" of 5,000 yuan for 10 years, which was enough for his family to live a lifetime.

"The villain has seen His Highness."

Zheng Hao quickly stood up, with a smile on his face, and gave Zhao Hong a salute.

"Lao Zheng, don't be polite. Is it because the ironshop is going to be bought by the government, so you are depressed? ”

Zhao Hong asked with a smile. There are some things that can be enjoyed and may not be replaced by money.

"Your Highness, the ironshop is the lifeblood of the villain. The government bought it, and the villain was a little reluctant in his heart! ”

Zheng Hao's face was full of grievances.

This Zhao Hong, who doesn't go to the wind and snow, spends all day drinking, hides in the ravines and ravines all day long to do these boring things.

Does he have a ...... in his brain? Sick?

Is there anyone like him in the world?

"Lao Zheng, the heavy weapon of the iron smelting country, the imperial court to take it back, is also a helpless move."

Zhao Hong said solemnly, aggravating his tone.

Once the new technology of iron smelting spreads, the Jin people will have nothing, and if it reaches the Tatars, it will be a big trouble.

"Wouldn't it be better for the craftsmen to be under the control of the Ministry of Industry of the Imperial Court, and to have no errands and to hold the money? Everyone's life is better, so you can see better. ”

"That being said, the villain ...... in his heart"

Zheng Hao's eyes flickered, his mouth was reluctant, and he didn't know if it was true or not.

"Lao Zheng, come, sit down and drink tea!"

Zhao Hong looked at the table at the door, there was a pot of hot tea on it, and the aroma was curling.

"The villain doesn't dare!"

Zheng Hao nodded and bowed, with a smile on his face, but he didn't dare to sit down.

There is a difference between respect and inferiority, and the noble and the low know that although Zhao Hong has no shelf, he is not arrogant enough to sit on an equal footing with the prince.

"Sit down. There are no outsiders here, let's drink tea! ”

Borrowing flowers to offer Buddha, Zhao Hong poured a cup of tea for Zheng Hao and motioned for him to sit down.

What's the point of putting up those useless shelves? He wasn't so shallow.

"The spring water is clear, the new tea before the rain, it's delicious! When I was in Lin'an City, why didn't I drink such a good tea? ”

Zhao Hong sipped the tea and shook his head slightly, as if he was enjoying it.

"Your Highness, the mountains and rivers are delicious, and the charcoal fire is enough. If it is an ordinary family under the mountain, it is not easy to boil water, let alone drink good tea! ”

Zheng Yuanwai started from scratch, although he was rich, he was still a poor man in his bones.

"Is it so troublesome to boil water?"

Zhao Hong leaned back in the chair, sipping tea, carelessly.

Such good water is not something that can be drunk casually in Lin'an City.

"Your Highness, the key is that it is not easy to light a fire every time, and it will make you disgraced. Therefore, His Highness is stained with the light of the iron furnace of the iron mill! ”

Zheng Hao pouted and said, Zhao Hong opened his eyes and couldn't help but be stunned.

It's so hard to boil water, and if there is no gas stove, is there no charcoal stove?

"Your Highness, the countrymen all burn straw and wheat stalks, and sometimes it is more difficult to make a fire when the firewood is flushed on rainy days."

Zheng Hao said with a smile, standing and drinking tea.

"Lao Zheng, brother, I'll teach you a trick to make up for the loss of your iron workshop."

Zhao Hong thought for a moment and remembered something.

Perhaps, this matter is good for people's livelihood and can liberate women from the stove.

"What is your highness's trick?"

Zheng Hao was also interested.

Zhao Hong is a skilled craftsman, and he is familiar with strange skills and tricks, and he is ashamed of himself.

"Lao Zheng, call your blacksmith, I have my own explanation, keep your blind dog eyes!"

Zhao Hong laughed and said, no liver and no lungs.

He picked up a pencil and drew on the paper on the table.

Since I was a child, I have used honeycomb coal and coal stoves, and I have made many of them, and the honeycomb coal stoves and honeycomb coal machines are also too ripe to be cooked.

"Your Highness, this is what you call a coal hammer and a furnace? This is the lump of coal? ”

The blacksmith came over, Zheng Hao and he looked at the coal stove and honeycomb coal machine on the drawing, and asked suspiciously.

The coal machine is not difficult to build, the key is briquettes, what is the method?

"Remember, charcoal and clay are somewhere between four to one and three to one. Honeycomb coal is put into the honeycomb coal furnace and a fire is lit once, only a few pieces of coal are needed a day, and there is no need to make a fire all year round. Boil water for cooking, room heating, very convenient! ”

Zhao Hong smiled proudly and continued to drink tea.

A stove for honeycomb coal, and a stove for three honeycomb coals, one large and one small, should be enough for cooking and making tea.

"No fire all year round?"

Zheng Hao and the blacksmiths still didn't believe it, their eyes were full of doubt.

Of course, practice is the only criterion for testing truth! This ability is handed over to you, it is enough to make up for the loss of your iron workshop! ”

Zhao Hong patted Zheng Hao's fat shoulder and said it solemnly.

"You sell yours, but I want to make it clear that the patent for this stove and briquettes is mine. In addition, for every stove sold, plus 100 briquettes, I still have to charge a penny in royalties. ”

"Second uncle, you go down to get it, if you don't understand, come back and ask me."

Zheng Hao walked away the half-believing blacksmiths and smiled.

"Your Highness, if it can really be done, what kind of fee will the villain pay you for one percent!"

Zheng Hao looked around and found that there was no one, so he lowered his voice and spoke.

"Your Highness, the villain has a reluctant request, and I ask Your Highness to allow it."

Zhao Hong looked at Zheng Hao, whose eyes were flashing, and nodded.

This fat man has a flexible mind, speaks evasively, and must not hold back any good fart.

"Lao Zheng, your own people, if you have something to say, if you have a fart, let it go!"

Zheng Hao helped him, and if he could help, he would definitely be duty-bound.

"Your Highness! Dalang, come here! ”

Zheng Hao smiled and shouted at the iron workshop behind him.

Then, a fat young man came out, Mount Tai pressed the top, and the dark clouds covered the sun, and walked straight over.

"Your Highness, this is the boss of the villain. Dalang, meet Your Highness! ”

Zheng Hao smiled and introduced the little fat man.

"Villain Zheng Tu, meet Your Highness!"

The little fat man stepped forward and saluted Zhao Hong, under great pressure.

He was called the little fat man because he was young, but he was actually bigger, taller and stronger than his father's tonnage.

"Zheng Tu, are you a butcher?"

Zhao Hong joked.

The tall and fat man in front of him, a mountain-like young fat man, reminded him of Zheng Tu, the "town of Guanxi" in the Water Margin.

"Your Highness, the dog has followed the villain to smelt iron since he was a child, and he has gone to school, and he likes these strange tricks the most. How can it be a butcher? ”

Zheng Hao introduced his son seriously.

"Just kidding, don't mind. The son inherits the father's business, good! Lao Zheng, have something to say! ”

Zhao Hong also put away his smile and was serious.

"Your Highness, the villain wants Da Lang to follow His Highness. You just say that this iron mill must have a reassuring person to watch. ”

Zheng Hao made a self-recommendation of being virtuous and not avoiding relatives.

"Your Highness, the villain has a little experience about casting artillery, and I want to talk to you about it."

Zhao Hong hadn't spoken yet, and the fat man had already spoken with great interest.

"Oh, you tell me!"

Zhao Hong nodded, also interested.

"The villain thinks that it is better to use a sand mold than a clay mold. Not to mention the clay mold, it is easy to get on the iron pipe and has trachoma. But the sand mold is much stronger, the sand mold is easy to dissipate heat, can breathe, and the molten iron can slowly cool down to form gray iron. Gray iron has good toughness and is also easy to cut with knives. ”

Zheng Tu talked eloquently, looking a little scolding Fang Xuan.

"So, do you have some experience?"

Zhao Hong's heart moved, and he sat up straight unconsciously.

Masters are in the folk. This is not a joke.

"Your Highness, Shaoxing Mansion has made assault muskets and earth-shaking thunder, and the villain has helped, and the sand mold and clay mold have been used, so I know some of the truths of casting firearms."

Zheng Tu was modest and high-spirited, and it seemed that he had a few brushes.

"Back to His Highness, the few cannons cast in front of him were melted by the dogs, and he said that the barrels were rough and useless. Inuko has already prepared some sand molds for pouring the barrels. He used to cast iron pipes, and he tried it! ”

Zhao Hong was still surprised, and Zheng Hao lost no time in praising his son.

Tian Yi was slightly embarrassed. Speaking of which, he just cast the artillery in accordance with Zhao Hong's explanation, and didn't think too much about it.

"Good! Zheng Tu, go on! ”

Zhao Hong looked at Zheng Tu appreciatively and encouraged him to continue.

Professional things must be done by professional people, this is the right principle.

"Your Highness, the inside of the iron pipe is drilled and polished smoothly, and it is completely possible to use water to help cool down and avoid damage to the knife, and use the fixed knife to drill and grind the inside of the iron pipe. It can not only ensure that the pipe wall is smooth, but also keep the pipe hole straight, ensure the quality of the barrel, and also shoot farther. ”

Zhao Hong was surprised. This kid has some skills, can't he also come from time in time, right?

"Then there is no need to cast hollow artillery, build a few waterwheels, fix the column and knives, and dig it out directly from the column?"

Zhao Hong's words made Zheng Tu stay for a moment, and then he nodded, his face full of excitement.

"Your Highness, this is a great idea! The chamber of the cannon thus made is smooth and straight, much better than the cast. However, if you use a cylinder to dig in a rotary cut, it may be very tool-intensive! ”

"Good! Don't be afraid to spend knives, just try it! ”

Zhao Hong breathed a sigh of relief.

It seems that this kid didn't come through time, otherwise he wouldn't have known about the solid drill cannon.

"Zheng Tu, the sand mold for casting cannons, you must be ready."

Zhao Hong looked at Zheng Tu's excited appearance and asked directly.

Whether it can be reused depends on whether it is wasted. It's good to be ambitious, but talent also has to match. Many times, talent does not deserve ambition, which is a very painful thing.

"Your Highness, the villain is ready to cast the cannon at any time."

Sure enough, Zheng Tu was full of confidence and replied with great interest.

"Good! Check it out! ”

Zhao Hong stood up and said heartily to Zheng Hao, who was smiling all over his face.

"Zheng Yuanwai, it's really a dog father without a tiger!"

If you think of a way and can solve it yourself, this is an out-and-out talent.

Looking at the back of Zhao Hong's departure, Zheng Yuanwai shook his head ignorantly.

This boast just doesn't sound right.

"Don't look at it! Hurry up and build a stove and a coal hammer! See if it works? ”

Zheng Hao shouted at the blacksmiths, and his heart was also suspicious.

Can this honeycomb coal, mixed with earth and charcoal, really ignite? It can't be bluffing, right?

The dignified prince of the Song Dynasty, how could he understand so many tricks and tricks?
